Abstract: A wear assembly to protect the front edge of an excavating bucket, which is secure, stable, easy to use, readily manufactured, and provides increased safety, and which eliminates any need for holes to be formed in the lip. The wear assembly includes a wear member that has a pair of legs to straddle the front edge of the bucket. One of the legs defines an axial slot, which has opposing grooves for receiving rails of a boss fixed to the bucket. The grooves narrow in a forward direction to permit easier installation and removal of the wear member, to permit use of side wings without interference from adjacent wear parts, and to enable enhanced resistance under some loads.

Abstract: A wear assembly for protecting a structure, such as an excavating bucket, from wear includes a lock for securing the wear member in place. The lock includes a take-up element for tightening the fit of the wear member, a latch to retain the lock in the assembly during use, and an arrangement for resisting loosening of the lock. With the assembly, the lock is able to effectively tighten the fit of the wear member on the lip, resist loosening of the fit, and facilitate easy removal of the lock without a concomitant increased risk of lock ejection.

Abstract: A wear assembly includes an adapter with a nose, a wear member with a socket to receive the nose, and a lock to secure the wear member to the adapter. The nose and socket include complementary rails and grooves that vertically diverge as they extend from the front of the nose. The lock can have a tapered construction.

Abstract: A wear assembly provided with a tapered opening and a complementary tapered lock wherein the lock can be pried into and from the opening to thereby eliminate the need for hammering. The lock is formed with a body and a latch that is movable between a hold position where the latch is engageable with a stop in the opening to releasably retain the lock in the opening and a release position where the latch disengages the stop.

Abstract: A wear assembly that includes a wear member and a boss to define an opening for receiving a lock forward of the front edge face of the lip which can mount the wear member in a stable and balanced manner without a through-hole in the lip. The wear member includes an aperture and a rib to define bearing faces on opposite sides of a central plane of the lip. The boss includes rails to hold the wear member in place, and a brace at the rear end, which supports the rails on the boss, abuts the rear of the wear member to reduce the loading on the lip, and deflects earthen material away from the wear member under reverse loading.
